Silva Tech 4O Accelerator Speed and Distance Watch Series

Whether you are a hardcore adventure hiker, an avid runner, or simply looking to count your doctor's recommended 10k steps a day, an Accelerator Series watch fits the bill. Advanced accelerometer technology provides highly accurate readings of a user's speed, distance, and caloric expenditure via a simple wrist watch sensor, eliminating the need for funny looking foot pods or belt clip sensors. Accelerometer technology is 95+% accurate, and much more dependable than traditional pendulum type (ball bearing) pedometers. Silva Accelerator watches make a great alternative to GPS for indoor training. The Accelerator Series is the perfect combination of accurate readings, simplicity of use, and stylish design.

Technology

The Gadgetry

The underlying technology in the Accelerator Series Watches is an accelerometer sensor. Accelerometers are used to measure acceleration. Originally developed during the Space Race to replace outdated gyroscopes, accelerometers can be found in a diverse range of today's products such as automobile air bags and tilt meters. In the Accelerator watch, a user's movement (acceleration) produces varying degrees of electric current within the sensor, allowing the watch to detect different levels of acceleration, and therefore measure speed and distance.

The Competition

There are really only a few different ways to calculate the speed and distance of human-powered, on-foot travel. The first was basic math, next came the mechanical pedometer, followed by satellite tracking GPS years later. Mechanical pedometers are cheap and abundant, but also highly unreliable. They operate on a simply pendulum clicker that relies on the walker's hip movement to count steps. Unfortunately, mechanical pedometers end up counting a lot of non-walking movements and assume that walkers are making consistent and repetitive steps.

GPS technology is impressive, but also expensive, complex, and not always ideal for outdoor activities or indoor training. Satellite signals can be lost indoors, in heavily forested areas, or behind large buildings (although newer receivers mitigate this) and receiving signals eats up batteries.

The Future

The Tech 4 O Accelerator Series fills the void between old mechanical pedometers and the expense of GPS. A simple, yet versatile, wrist-watch design can provide extremely accurate speed and distance data in all conditions.

Silva Accelerator Watch Features

Pedometer

Highly accurate step counter with adjustable sensitivity allows users to tune the sensors to their individual walking style. Doctors everywhere are now recommending 10k steps a day to maintain a healthier lifestyle.

Get off the beaten path! Free yourself from mileage markers at the track or trail! Pick a new route every day! The Accelerator can automatically distinguish between running and walking, and can calculate your average speed, distance, caloric expenditure, and total exercise time.

The Accelerator has a delayed step counter feature that differentiates between ancillary movements and actual steps. This feature provides users with the most accurate results by delaying calculation until it has registered 10 steps in a row to eliminate overly sensitive step counting.

The smart scheduling features allows users to set the pedometer to automatically start/stop counting steps at a predetermined time every day, so you'll never forget to turn it on

Personal Profile

This feature allows users to customize their watch to their specific body type and walking/running style. No matter how fast or slow, tall or short, each user can personally enter their weight, average walking stride, and average running stride in order to ensure accurate results.

Hikers can easily account for loaded pack weights.

Runners can dial in the stride length to account for varying terrain and/or speed workouts.

Quickly adjust weight and stride lengths as conditioning improves.

Chronograph

The accelerator series' powerful stopwatch features allow users to record exact results to within 1/100th of a second for up to 50 laps and a total time of 24 hours.

Although the watch has several advanced ways of calculating speed and distance, the old-school chronograph still has a place and purpose.

Countdown Timer

A simple countdown timer can come in real handy at times. Set it for 10 minutes as a quick reminder. Use it to monitor your running/walking pace and set speed goals.

Alternative Time Zone

Great for those that travel! Allows users to set and display an alternative time zone along with the current home time display. Never lose track of time no matter where you are.

Daily Alarm Mode

We are all creatures of habit in our daily routines. Great way to set a daily reminder or wake up alarm.

Excellent watch. It took a while to understand how to operate, but once I got over that hurdle, everything went well.
